Effect of pH on the secondary and tertiary structures of FCS1 at 20°C (A) CD spectra as a function of pH. The pH values were 3.0, 4.0, 6.0 and 7.0. (B) CD spectra as a function of pH. The pH values were 7.0, 8.0, 9.0 and 10.0. (C) Effect of pH on the tertiary structure of FCS1 monitored by intrinsic fluorescence spectroscopy. The pH values were 3.0, 4.0, 6.0 and 7.0. (D) Effect of pH on the tertiary structure of FCS1 monitored by intrinsic fluorescence spectroscopy. The pH values were 7.0, 8.0, 9.0, 10.0.
